Question
A 36-inch culvert will cross a roadway beneath the low point of an 800 foot, equal tangent, sag vertical curve. The curve connects an initial grade (G1) of –1.8% with a final grade (G2) of +3.3%. The stationing of the PVI is 150+00 and the elevation is 243.00 feet. To provide adequate cover to prevent frost-heave, the top of the culvert is to be placed 30 inches below the pavement surface. Determine the stationing and elevation of the bottom of the trench in which the culvert should be placed. Assume negligible thickness of the culvert walls.
